An Overview of the CCSP Domains
Introduction to the CCSP Domains
Cloud computing has proved itself as a powerful means for organizations to grow their business in terms of cost and time efficiency, profitability and overall business growth. However, with the increase in adoption rate of cloud computing by organizations, one has to understand and study its security implications in order to successfully implement it for long term profitability of a business. For this, organizations need experienced and competent professionals who are equipped with adequate knowledge and skills of cloud security. Organizations need Certified Cloud Security Professionals (CCSPs).
Cloud security certification equips professionals with in-depth knowledge and competency resulting from hands-on experience in software, information, cloud computing and cyber security. It is supported by the Cloud Security Alliance (CSA) and the International Information System Security Certification Consortium (ISC)².
(ISC)² and CSA are renowned organizations in information security and cloud industries respectively and this combined step offers a vendor-neutral professional certification in cloud security. The certification is a demand of the global information security industry as cloud computing has evolved as an area of concern requiring security considerations. (ISC)² strives to address security within the cloud environment so that Information security and IT industry can continue to flourish. Cloud Security Alliance (CSA) gives subject matter experts, governments, associations, etc. a platform to provide education, research, certification, products to provide benefit to all stakeholders.
CCSP has been designed for information security professionals who are already experienced in the field and have at least five years of combined full-time experience in information security and cloud security. In this article we will provide a brief overview of the six domains of knowledge of the CCSP which focus specifically on cloud computing, assuming the familiarity with and experience of the candidate in information security as already mentioned above.
